SHURFLO Pump Silencing Kit — 36" High-Pressure Flexible Hoses, 1/2" Swivel Fittings, Noise & Vibration Reduction

SHURFLO 94-591-01 Pump Silencing Kit is a complete noise- and vibration-reduction solution that replaces rigid plumbing connections with two 36" flexible high-pressure hoses and fittings to quiet RV, marine, and residential pump systems.

If your onboard or household water pump makes rattles, thumps, or transmitting vibrations into walls and cabinets, this kit gives you the flexible plumbing components to isolate the pump and cut down noise. Engineered for easy retrofit, the kit provides two 36-inch reinforced hoses with 1/2" female swivel fittings and two 1/2" x 1/2" NPT-M pipe nipples so you can connect directly to most SHURFLO-style inlet and outlet ports.

How does this kit reduce pump noise and vibration?

The flexible hoses absorb and decouple vibration that would otherwise travel from the pump into rigid piping and structure. Replacing hard plumbing with flexible connectors interrupts vibration paths and reduces rattles, humming, and structure-borne noise.

• 36" high-pressure flexible hoses dampen mechanical vibration.
• Swivel female fittings prevent torque transfer during start/stop cycles.
• Pipe nipples allow correct alignment without stressing the pump ports.

Will it fit my SHURFLO pump and plumbing layout?

The kit is built to match common SHURFLO pump inlet/outlet dimensions and standard 1/2" piping. The included 1/2" female swivel fittings and 1/2" NPT-M nipples make it adaptable to many RV, marine, and household plumbing configurations when standard-sized ports are used.

• 1/2" female swivel fittings for direct connection to pump ports.
• Two 1/2" x 1/2" NPT-M pipe nipples for threaded transitions.
• 36" hose length accommodates tight and offset installations.

How difficult is the installation and what tools are needed?

Installation is straightforward for anyone comfortable with basic plumbing connections. The hoses and fittings connect directly to the pump inlet and outlet; thread sealant or tape and standard wrenches are typically all that's required.

• No special tools beyond adjustable wrenches and thread sealant.
• Swivel fittings ease alignment, reducing need for pipe bending.
• Typical install time is short—often under an hour on accessible pumps.

Does the kit handle typical RV and marine pressures?

The hoses are rated for high-pressure pump use and are intended for potable and non-potable water systems commonly found in RVs, campers, and boats. The robust construction keeps connections secure while providing the flex needed to isolate vibration.

• Reinforced hose construction supports pump operating pressures.
• Female swivel fittings maintain leak-resistant seals under load.
• Durable materials resist kinking and wear in mobile environments.

Who is this for? The SHURFLO 94-591-01 Pump Silencing Kit suits RV owners, boaters, and anyone with a compact high-pressure water pump who wants to cut down audible noise and structural vibration. It's particularly useful when an existing rigid plumbing setup transmits pump movement into cabinetry or hull structure. If you need a simple, reversible retrofit that improves living-quarters quietness and reduces wear on pump ports, this kit provides the hoses and fittings to get the job done quickly and reliably.
